Two groups of eight 2-yr-old ewes were fed a low manganese (Mn) synthetic diet (8 ppm Mn) either with or without Mn supplementation (60 ppm Mn). The diets were fed for a 5-mo period prior to breeding and throughout gestation. Manganese supplementation of the diet resulted in higher blood Mn concentration. More services per conception were required for the ewes fed the low Mn diet than were required for the ewes fed the Mn-supplemented diet. The calcium content of kidney and muscle tissues, the magnesium content of spleen and the zinc content of the heart were found to be lower in ewes fed supplemental Mn, while the zinc content of the spleen was found to be higher. The calcium levels in the heart and kidney and iron levels in the liver and lung were higher in the day-old lambs born to Mn-supplemented ewes, while the magnesium level in the heart was lower. It is suggested that the calcium response of the ewes on low Mn diet to the physiological demands of fetal development may have been impaired by a reduction in dietary Mn.

Abstract Objective To measure the level of hair Mg, as well as its level in serum, in patients with epilepsy and compare them to the levels found in non-epileptic age and gender matched children, and to explore any potential correlation between either serum or hair level of magnesium and seizure characteristics in children with idiopathic epilepsy. Methods An observational cross-sectional study including 50 children with idiopathic epilepsy and 100 non-epileptic age and gender matched control subjects. Cases were subjected to full history taking, examination and measurements of serum and hair levels of magnesium, control subjects only had their serum and hair level of magnesium measured as for the cases. Results The mean serum magnesium was 29.11 ± 13.42 ug/ml for cases and 27.67 ± 7.24 ug/ml for controls and the median hair level of magnesium was 42.22 ug/g with IQR of 25.9 - 56.82 for cases and 38.6 ug/g with IQR of 25.21 - 61.25 for controls. No statistically significant difference was observed between both groups as regards either serum or hair magnesium levels. No statistically significant correlation was observed between either hair or serum levels of magnesium and seizure characteristics though the correlations were nearing statistical significance for the hair magnesium content. Conclusion Hair magnesium level may be better correlated to seizure characteristics and control than serum levels in patients with epilepsy.

In a two-pot experiment of Phaseolus vulgaris L., the influence of K and Mg gradated doses upon K, Mg and Ca content in the pods, stem and leaves was studied. The content of cations changed significantly in individual parts of the plant. The highest content of potassium was found within the dry matter of the pods (it exceeded 4%) and stalk (3–4%). The highest content of calcium (3–4%) and magnesium (0.4–0.8%) was found within the dry matter of the leaves. The effects of K gradated doses were revealed significantly in its higher content increase mainly in the leaves (by as much as 83%) and the decrease of calcium content (31%) and magnesium content (37%) was observed in the leaves and less in the stalks. The effects of Mg gradated doses were revealed in the non-significant increase in its content in the leaves and stalks and the decrease of the potassium content in the leaves (by 19%) and in stalks (11%) and even in the decrease of the calcium content (52%) mainly in the pods.

Kazakhstan currently faced with a serious deterioration in the state of natural resources and the environment in all the most important environmental indicators. Almost a third of the agricultural land is now degraded or is seriously threatened, and more than 10 million hectares of potentially arable land in the past has been abandoned. The article presents the results of research to improve the well-being of reclamation of soils of southern Kazakhstan. The studies were conducted in the field and in the lysimeters, with laying of experiments on the introduction of phosphogypsum and deep loosening. The results showed that the most promising is the option with the introduction of 5...7 t/ha of phosphogypsum and deep loosening in which the reduced alkalinity of soils, it improves soil alkalinity magnesium that is reduced magnesium content in the soil, increases the content of non-toxic salts and productivity of legumes. Soil application of phosphogypsum at the rate of 5 t/ha increase the calcium cations in the rooting zone of soils. On one of the variants of the experience as a result of using phosphogypsum norm 5 t/ha calcium content increased on 4.67 times. On option, where they grow soybeans, the calcium content amounted to 0.046 %. The introduction of phosphogypsum reduces the alkalinity of soils and reduces the amount of magnesium and increases the content of non-toxic salts СаЅО4, increases the yield of leguminous and cereal crops. Soybean yield in the control variant was 11.27 kg/ha. Soil application of phosphogypsum at the rate of 5 t/ha increased its yield is 31.4% compared to the control variant, the variant with deep loosening – 15.1 %. In the variant where the soil amended phosphogypsum and the deep tillage, soybean yields by 34.1 % higher than the control variant. Therefore, the proposed techniques improve the soil of magnesium solontsovaya the South of Kazakhstan are promising.

Just as high yields and quality of plantains, a cooking banana widely used throughout the Tropics, were produced by planting directly in the sod, followed by strip cultivation for erosion control, as after complete land preparation and clean cultivation on a typical latosol in the Humid Mountain Region of Puerto Rico. The effects of plant population and of fertilization with sod-planting and strip cultivation were studied. Increasing the number of trees from 500, which is standard practice, to 800 per acre increased yields by 4 tons of fruit. No further increase resulted from increasing the population to 1,300 trees per acre. Plantains responded strongly in yield to applications of 200 pounds of nitrogen and of phosphoric acid per acre on this soil, which contained 0.20 percent of nitrogen and less than 40 pounds of dilute acid-soluble phosphorus per acre. No response to lime, magnesium, or potassium was evident on this soil which had a high content of these nutrients in available form. The nitrogen, phosphorus, and potassium contents of the plantain leaves increased with applications of these nutrients as fertilizer, but applications of magnesium and calcium did not affect the content of these nutrients in the leaves. Leaf contents of 2.8 percent of nitrogen, or 0.13 percent of phosphorus, indicated a deficiency of these nutrients, while a calcium content of 0.60, a magnesium content of 0.24, and a potassium content of 2.8 percent indicated a sufficiency. The experiments showed that 8 tons of plantains yielding o tons of edible pulp comparable in feeding value to potatoes, or 2 tons of dry matter with a caloric content similar to that of corn, can be produced per acre with excellent erosion control on steep lands in the Humid Mountain Region of Puerto Rico.

Abstract Supplemental arginine (Arg) during gestation purportedly benefits fetal development. However, the benefits of a gestational Arg dietary strategy in commercial production are unclear. Therefore, the objectives of this study examined Arg supplementation during different gestational stages and the effects on gilt reproductive performance. Pubertal gilts (n = 548) were allocated into 4 treatment groups: Control (n = 143; 0% supplemental Arg) or 1 of 3 supplemental Arg (1% as fed) treatments: from 15 to 45 d of gestation (n = 138; Early-Arg); from 15 d of gestation until farrowing (n = 139; Full-Arg); or from 85 d of gestation until farrowing (n = 128; Late-Arg). At farrowing, the number of total born (TB), born alive (BA), stillborn piglets (SB), mummified fetuses (MM), and individual piglet birth weights (BiWt) were recorded. The wean-to-estrus interval (WEI) and subsequent sow reproductive performance (to third parity) were also monitored. No significant effect of supplemental Arg during any part of P0 gestation was observed for TB, BA, SB, or MM (P ≥ 0.29). Offspring BiWt and variation among individual piglet birth weights did not differ (P = 0.42 and 0.89, respectively) among treatment groups. Following weaning, the WEI was similar among treatments (average of 8.0 ± 0.8 d; P = 0.88). Litter performance over 3 parities revealed a decrease (P = 0.02) in BA for Early-Arg fed gilts compared with all other treatments, whereas TB and WEI were similar among treatments over 3 parities (P > 0.05). There was an increased proportion of sows with average size litters (12 to 16 TB) from the Full-Arg treatment sows (76.8% ± 3.7%) when compared with Control (58.7% ± 4.2%; P = 0.01); however, the proportion of sows with high (>16 TB) and low (<12 TB) litters was not different among treatments (P = 0.20). These results suggest that gestational Arg supplementation had a minimal impact on reproductive performance in first parity sows. These data underscore the complexity of AA supplementation and the need for continued research into understanding how and when utilizing a gestational dietary Arg strategy can optimize fetal development and sow performance.
